error TS2339: Property 'dataCy' does not exist on type 'cy & CyEventEmitter' about quasar-testing

Hey there, are you sure you followed the upgrade guides while migrating from Cypress AE v4 to latest v5?

Both of these:

• https://github.com/quasarframework/quasar-testing/tree/dev/packages/e2e-cypress#upgrade-from-cypress-ae-v4
• https://github.com/quasarframework/quasar-testing/tree/dev/packages/e2e-cypress#upgrade-from-cypress-ae-v51-to-v52-onwards

This seems a problem due to misconfiguration / poorly upgraded environment, as this problems isn't present into new installations AFAIK

Are you able to provide specifics of what I might miss? There are a lot to check.....

[IlCallo]

I honestly have no idea, have you tried generating a new project with latest Cypress AE and comparing the Cypress configuration files?

I made some progress. However, even starting with a fresh new quasar project installing the AE hits the following error:

 $ n test

Are you're running Cypress tests with... Jest?
How did you even manage to do that?

The scaffolding for Jest AE and Cypress AE are optimized to avoid mixing the 2 testing framework

As stated by the docs, these are the commands you should use to run Cypress tests
